I'm working on the new steering return lines today.
Relocated the new plate cooler in the grill, and lines come straight down, instead of to the left or right.
The stock return lines have rubber hose on them, but the metal tubes are bent so they point to the pass side, from the racks port area. I want to change the bends so they point forward, not to the pass side. This is proving to be a bit harder than anticipated. LOL!
I could cut off the ends of the tubes, right before the bends, but that will remove the extruded flare at the ends. I really want to keep those flares, for the hoses. I am afraid I will kink the lines, trying to bend by hand, and really don't want to pack them with sand. Might have to just leave them be for now, and live with the extra length of hose, until I figure this out. Might need to get some custom lines made at a shop. I'm not going to spend a couple hundred bucks on a proper tube bender just for this job.
Edit:
Had to skip a day wrenching on this because of rains. Wasted an entire Saturday cleaning inside the house instead.

Fast forward to Sunday....We have power assist again! Tons better now. Either blocked lines or cooler or both! Return to center is better, but not 100%. I think that's in the alignment?
Was able to get the cooler plumbed up with new 3/8 PS hose. Ended up using the screw clamps that came with it. Auto stores aren't stocking them anymore for some goofy reason. Special trip for nought.
Yeah, she a dirty girl right now. Needs a good sponge bath!
Had to make a temporary 1/4" thick bracket for the return line from cooler to rack, until I get a custom line made changing ends direction 180*. It keeps the 180* "U" radius over 3", which your not supposed to go under, so all good there.
For the return hose from Reservoir, to cooler, I decided not to use the brand spanking new line I just bought for it. (smh) It was better just to run a length of hose directly from the cooler to the tank. Routed moocho gooder's.
This stacked plate cooler is twice as big as the stock unit. It's mounted in the grille, in front of the trans cooler fan. When the fan is running, it sucks air through it pretty darn good. Did a smoke test to watch it in action. lol It should be pretty hard to see it once the grill is back on. It now hides the trans fan from view.
For size comparison....
So besides the actual steering wheel/column & intermediate shaft, everything in this system is brand new. What an expensive PITA! Might have cost more than the rig did, when it was acquired over a decade ago.
Ok, so I don't happen to have another 5.0 Explorer hanging around to compare stuff, but I know this negative Battery cable isn't supposed to be in front of the oil filter like it is. It's a total PITA to change the filter like that. I also noticed while doing this work, that that cable is about 1/4' from hitting the harmonic balancer. My only guess as to why it was put there by the 5.0 swap people, is the 4.0 cable is shorter than the 5.0 cable, and they called it good enough. Crazy.
I pulled it down by hand about 1/2" from the balancer. The frame bracket for it by the filter is there, but not being used. Cable won't reach it. Got that short man syndrome going on.
Grill is staying off until the new Headlights arrive. Might be a week or so. Going to try to clean it up (new paint) in the mean time.
Had about an hour left of daylight, and got a bit more done with the sheet metal wheel liners. This Mod is going to be a slow one, as it's something to do in between other jobs. Maybe installed by Spring? Cleaning needs to be a priority on this thing that's for sure. This power steering ordeal has made a mess of everything up front. Couple of wheeling trips in wet areas has left it's mark too. Frame needs a good once over with a wire brush, and another paint job needs to happen. Been a few years since I messed with it. I'm such a slacker!
